Laparoscopic appendicectomy for a large appendiceal mucinous neoplasm

We present the case of a 71-year-old male with long standing inflammatory bowel disease (IBD) who was diagnosed with an appendiceal mucinous neoplasm (AMN). Preoperative CT scan confirmed a 9cm cystic lesion confined to the appendix and the patient underwent laparoscopic appendicectomy. In this case, given the size of the neoplasm and the adhesions to neighboring structures, ileo-caecal mobilization was carried out using bipolar forceps. The base was identified and divided with an Endo-Gia Stapler and retrograde appendicectomy was then performed. The post-operative course was uneventful; the patient was discharged on post-operative day 3. The histologic report confirmed a low grade appendiceal mucinous neoplasm (LAMN) with negative margins.
